Antarctic dense water overflows

Ocean modelling visualisations

Explore cutting-edge ocean simulations at ANU, showcasing sea temperature changes and dynamic oceanic flows, for insights into our planet's vital water systems.

Antarctic Ice Shelf melting in the Weddell Sea

Ice shelf melting beneath the Filchner-Ronne Ice Shelf and Antarctic Bottom Water overflows visualised using the simulation of Pan-Antarctic version of ACCESS-OM3 (1/12o horizontal resolution). Credit: Claire Yung with help of ACCESS-Vis and Prof Andy Hogg.
 

 

 

Evolution of sea surface temperature 

High-resolution simulation of the global ocean, showing the evolution of sea surface temperature over a 3-year cycle.

This animation shows the rich dynamics of eddies and jets in the Indian Ocean sector of the Southern Ocean, which act to mix ocean waters. It shows a high-resolution (1/20°) regional simulation of the Southern Ocean, including a peek at a submesoscale (1/80°) resolving nested simulation.

Dense Shelf Water overflows and formation of Antarctic Bottom Water in the Ross Sea 

The visualisation was produced through a collaboration between Andy Hogg, UNSW collaborators and the National Computational Infrastructure’s VizLab team. It reveals waterfalls of cold dense water that plummet two kilometres off the Antarctic continental shelf into the abyss, forming the bottom water of the global oceans.
